Research suggests that the threat from invasive non-native species (INNS) is growing. Biological invasions by INNS harm native species and habitats and can have economic impacts. Biosecurity measures can be adopted to prevent the introduction and spread of INNS. This POSTnote summarises the drivers and impacts of INNS and the measures needed to meet national and international environmental targets.
Greenhouse gas (GHG) emissions from the iron and steel industry make up 14% of industrial emissions in the UK. Decarbonisation of the steel industry is needed if the UK is to meet its target of net zero GHG emissions by 2050. This POSTnote outlines current steelmaking processes in the UK, the technologies and measures that can be used to reduce CO2 emissions, and the supporting infrastructure and policies that could enable a ‘green steel’ industry in the UK.
This POSTnote will summarise the evidence base for increasing the resilience of habitats to climate impacts and outline the current approaches to implementing measures in the different nations of the UK.
